비특이성 허리통증환자 큰허리근의 근두께와 근긴장도, 골반각도에 심부횡적강찰법과 수동신장운동, 능동적근육이완기법이 융합적으로 미치는 영향

The Fusion Effect of Deep Transverse Stroking, Manual Stretching Exercise and Active Muscle Release Technique on Psoas Major Muslce Thickness and Muscle Tone and Pelvic Angle of Non-specific Low Back Pain Patient

본 연구는 비특이성 허리통증환자에게 큰허리근을 신장시킬 수 있는 세 가지 중재방법인 심부횡적강찰법, 수동신장운동과 능동적근이완기법이 큰허리근의 근두께와 근긴장도, 골반 각도의 변화에 미칠 수 있는 융합적인 영향과 그 차이를 알아보고자 한다. 큰허리근의 근두께는 심부횡적강찰법 $0.19{\pm}0.16cm$(p<0.05), 수동신장운동 $0.18{\pm}0.14cm$(p<0.05), 능동적근이완기법 $0.43{\pm}0.35cm$(p<0.05) 적용 후 유의하게 감소하였다. 골반각도는 심부횡적강찰법 $4.48{\pm}1.63^{\circ}$ (p<0.05), 수동신장운동 $5.36{\pm}2.04^{\circ}$(p<0.05), 능동적근이완기법 $7.24{\pm}2.23^{\circ}$(p<0.05) 적용 후 유의하게 감소하였다. 큰허리근의 근긴장도는 심부횡적강찰법 $0.96{\pm}0.93Hz$(p<0.05) 적용 후 유의하게 감소되었으나, 수동신장운동 $0.87{\pm}1.20Hz$(p>0.05), 능동적근이완기법 $0.82{\pm}0.98Hz$(p>0.05) 적용 후 유의한 차이가 나타나지 않았다. 세 가지 중재방법 간 큰허리근의 두께와 근긴장도, 골반 각도의 변화량을 비교하였으나 유의한 차이는 나타나지 않았다. 큰허리근 근두께와 골반각도를 변화시키기 위해서는 세 가지 중재방법을 환자분의 상태와 환경에 맞게 적절하게 적용하면 될 것이고, 큰허리근 긴장도를 변화시키기 위해서는 심부횡적강찰법이 더 효과적이라고 사료된다.

The purpose of this study was to investigate the fusion effects and difference them of the deep transverse stroking, manual stretching exercise and active muscle release technique on psoas major muscle thickness and muscle tone, and pelvic angle in non-specific low back pain patients. Psoas major muscle thickness was significantly decreased after the application of the deep transverse stroking $0.19{\pm}0.16cm$ (p <0.05), manual stretching exercise $0.18{\pm}0.14cm$ (p <0.05), and active muscle release technique $0.43{\pm}0.35cm$ (p <0.05). The pelvic angle was significantly decreased after the application of the deep transverse stroking $4.48{\pm}1.63^{\circ}$ (p <0.05), manual stretching exercise $5.36{\pm}2.04^{\circ}$ (p <0.05), and active muscle release technique $7.24{\pm}2.23^{\circ}$ (p <0.05). The Psoas major muscle tone was significantly decreased after application of the deep transverse stroking $0.96{\pm}0.93Hz$ (p <0.05), but manual stretching exercise $0.87{\pm}1.20Hz$ (p> 0.05) and active muscle release technique $0.82{\pm}0.98Hz$ (p> 0.05) there was no significant difference after application. There were no significant differences between the three intervention methods in the pelvic angle and psoas major muscle thickness and tone changes. In order to change psoas major muscle thickness and pelvic angle, three intervention methods should be applied appropriately according to the condition and environment of the patient, and deep transverse stroking is more effective for changing psoas major muscle tone.
